ALBERT I-I. REIBEE, OF CHICAGO, ILLINOIS, ASSIGNOR, BY MESNE ASSIGNMENTS, TO IvIORKRUM-KLEINSOHMIDT CORPORATION, OF CHICAGO, ILLINOIS, A CORPORATION OF DELAWARE.

Application filed September 2, 1922, Seria1 No. 585,671. Renewed March 31, 1927.

In the transmission 01'' messages by printing telcgraphs, employing the Baudot or any other code, it has become desirable to provide means tor the transmission and reception of auxiliary signals, including service signals, such as start, stop, re-run, repunch, etc, which are not sent by means of perforated tape or keyboard, but on account of their frequent recurrence, are trans:- mitted by special code wheels, or similar means, and received on audible devices, such as bells, or otherwise.

One form of sending devices of this character is shown in U. S. Letters Patent 150. for U. S. Letters Patent, Serial No. 50%,862, filed October 3, 1021. These devices are intermittently operated, and provide for the interruption of the regular message and ot the operation or the tape feeding mechanism at the sending station, while service or auxiliary signals are sent.

The present invention relates to a receiving unit of a printing telegraph system, and

' an audible signal, such as a bell therein,

which invariably will be operated after a blank signal is received from the sending unit. The usual start impulse operates a control'relay having two contacts, one of which, in conjunction with the spacing contact-point of the line relay, closes a locking circuit for the control relay, while the other contact, when the control relay is deenergized, short-circuits the signal bell magnet ot the receiving unit and prevents the bell from ringing.

The drawing discloses a diagrammatic view of a part of the receiving unit used in the reception oil audible auxiliary signals, in which indicates a transmitting station connected by means of main line 11 to polarized. line relay 12 of a receiving station. Contact tongue 13 plays between spacing contact point 14: and marking contact point 15. Conductor 16 leads to control relay 17 while a second conductor 18 connects control .relay 17 with start magnet 19 and, by means of conductor 20, with start segment 21 of distributor head 22. Brush arm 23 travels in the usual manner over the face of distributor head 2 and the brushes on brush arm connect the outer segmented ring of the distributor head to battery ring 2 1. The latter is connected by means of conductor 25 to positive pole of battery 26. Conductor 27 leads from negative pole of battery 26 to contact tongue 13 of line relay 12.

Control relay 17 is provided with two contacts. preferably on one and the same armature, 28 and 29, one of which, contact 28, is arranged to close locking contact point 30 and connect one winding of relay 17 over conductors 31 and 25 to positive pole of battery 26. A second conductor 32, containmg a suitable resistance leads to spacing contact point 14 of line relay 12.

The selector unit contains selector magnets 33, 3 35, 36 and 37, connected as now known in the art, to segments 1,2, 3, 4 and 5, of distributor head 22. Common conductor 38 connects the selector magnets over a resistance and conductor 16 to'marking contact point 15 of line relay 12. The negative pole of battery 26 is connected, by means of conductor 10, to sixth impulse magnet 41, and out-going conductor 42 thereof leads to wire joint 43 and. by means of conductor 4-4, to magnet 45 of signal bell 46, while a second conductor 17 connects the out-going terminal of bell magnet 15, over wire joint 48 and conductor 49, to the sixth impulse segment 6 of distributor head 22.

Contact 29 of control relay 17, when the latter is deenergized, closes contact point 50, thereby short-circuiting signal bell magnet 45. A resistance 51 is placed across conductors 16 and 18, so as to make the right hand winding of control relay 1?, slow to release, when its circuit is opened at contact tongue 13, in passing from marking contact 15 to spacing contact 14.

Operation.

The drawing indicates that contact tongue 13 of line relay 12 is normally in contact with spacing contact point 14. hen the start impulse. is now received, tongue 13 moves over to marking contact point 15 and energizes control relay 17 over the following circuit: negative pole of battery 26, conductor 27, contact tongue 13, contact point 15, conductor 16, right hand winding of control relay 17, conductor 18, winding of start magnet 19, conductor 20, start segment 21, of

distributor head 29, brush arm 2, battery ring 24. and, over conductor 25, back to positive pole or battery 26. The eitcctof the closing of this circuit is the energization oi. control relay l7 and start magnet '19. Start magnet 19. When energized, releases brush arm 23, which begins to rotate over the face of distributor head 22. If new the start impulse received from transmitting station 10 is followed by a blank signal, containing, for instance, five spacing impulses, relay tongue 13 will move back against its spacing contact. 14, brush arm 23 continues its rotation to sixth impulse segment 6, control relay 1'? will be locked up at its contact point 30 and s 'iacii'ig contact point 14, and when this condition prevails, bell magi'iet 45 is in series with sixth impulse magnet ll and, assuming brush arm 23 reaches sixth impulse segment 6, then bell ll will ring. it, howover, any one or more ol the 5-:clcclingr impulses are of marking polarity and energizing one or more of cctor lllltgllfllt; 33 to 37, inclusive, relay tongue 12% of line relay 11 will move over to n'ii-irltinn contact point 15, the locking circuit for control relay 17, is opened at spacing contact point lei. and locle ing contact point 30 of" control relay 1?, and control relay 1? will again. be dcenergized. it will be soon that when brush arm 2 passes sixth impulse segment (3, While control relay l7 is decnergized, contact 29 of control relay 1? closes contact point 50, bell magnet 45 will thereupon be short-circuited and he'll 46 will not ring.
